Former Memphis mayor Willie Herenton lashes out at local officials for not taking action on the city's pressing issues, saying he'd lost his "faith" in local politics. During a wide-ranging interview for this week's episode of 125 North Main, the former mayor discussed his time in office, the possibility of a political comeback, whether Memphians should march on the 50th anniversary of the death of Martin Luther King Jr., and about a new juvenile detention campus he's proposing in Downtown.
